What's Wrong?

When using anthropics/claude-code-action@v1 with plugin_marketplaces, the marketplace step fails with Executable not found in $PATH: "claude". The installer reports success (Location: ~/.local/bin/claude) but warns /home/runner/.local/bin does not exist.

What Should Happen?

The installer should create ~/.local/bin and ensure it's on PATH before the marketplace plugin step runs.

Error Messages/Logs

⚠ Setup notes:
    • installMethod is native, but directory /home/runner/.local/bin does not exist
    • installMethod is native, but claude command not found at /home/runner/.local/bin/claude

Steps to Reproduce

1. Use anthropics/claude-code-action@v1 with plugin_marketplaces on a fresh ubuntu-latest runner
2. Action installs Claude Code v2.1.53
3. Marketplace step fails — claude not on PATH
